DEVICE FOR RlVETlNG HOLLOW CYLINDERS.

SPECIFICATION forming part of Letters Patent No. 280,452, dated July 3, 1883. Application filed September 14, 1882. (No model.) Patented in Canada March 10, 1883, No. 16,450.

To all whom it may concern:

Be it known that 1, JAMES H. CLINoH, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Riveting; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to an improvement in riveting; and it consists in the application and use of a movable frame or carriage in connecti 011 with a sledge or holding-on set in the operation of riveting.

Heretofore it has been customary to secure the holding-on sledge by a rod, one end of which passes through a rivet-hole and is keyed thereto, while on the other end of the rod is formed a hook in which the handle of the sledge rests. The chief objections to this mode of securing the sledge are that the rod will often break down during the riveting onerati on, and also that considerable time is occupied in moving the rod from hole to hole. A stake resting on the shell has also been employed to support the holding-on sledge.

I will now describe my invention so that others skilled in the art may manufacture and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective View of the holding-on sledge or set supported by the carriage, and Fig. 2 is an end elevation of the same.

Like letters of reference indicate like parts wherever they occur.

In the drawings, a represents the holding on set, the face of which is provided with a cavity, a, which cavity is of such shape as to hold the head of the rivet b, fitting closely around the same, directing the resisting force in the proper direction, and preventing the head from being broken or bent-during the riveting.

Instead of the devices hereinbefore referred to for supporting the holding-on sledge or set, I use in the riveting operation a carriage, 0, having the standards or legs (Z, on the lower end of which are wheels or rollers 6. These standards cl are bolted together at their top ends, leaving a hole, f, into which fits a bar, g, having a slot, h, formed in its upper end, in which slot the handle or arm '6 of the holdingon sledge rests, while a man holding the end of the handle directs and keeps the head of the sledge in the desired position.

The bar 9 may be made adjustable on the standards (1 either by a screw-thread or by slots and keys; or different bars of different lengths may be inserted in the body of the carriage, according to the diameter of the boiler or other article to be riveted. The wheels of the carriage rest 011 the bottom of the boilershell, so that the carriage is moved with rapidity and ease as the shell is turned, and the holding-on sledge is therefore always held in the proper direction; The wheels of the car riage resting on different points of the boilershell, the force of the blows is distributed,

and the shell is not injured thereby.

Although I have described a particular form of carriage, specially adapted to the riveting of boiler-shells, I do not desire to limit myself to either this form of carriage or to this special use, as other forms suitable for other riveting may be employed; but,

Having thus described my invention, what I claim, and-desire to secure by Letters Patent, 1s

a holding-011 sledge having a cavity in the face thereof, substantially as and for the purpose specified.

In testimony whereof I have hereunto set my hand.

JAMES H. CLINOH.
